This should be easy:
Can I have a column in the grid that shows the invoice number for the most recent invoice for the customer in that row? I'd like to have it hyperlinked to open the invoice screen for that invoice.
In other words, the actions would be like:
Loop through the Invoice table where the FullName = the row's FullName
Retrieve the invoice number for the invoice with the most recent transaction date.
Like I said, should be easy but I don't see any Max/Min functions in the Actions environment.
